Abstract
A display device includes an integrated liquid crystal display and a backlight unit. The liquid crystal display is provided with a backlight system that includes a light-emitting element positioned along one or more sides of the display. In order to efficiently distribute and dissipate the heat produced by the light-emitting element, the backlight cover can cover the light-emitting elements and the area over the liquid crystal display. For shielding, the backlight cover can separate the display from an electronic circuit assembly. The backlight cover may be made monolithically of a heat-conductive material such as aluminum, as well as an electro-conductive material for shielding. The backlight cover may also provide mechanical support for the display device and mounting features to ease assembly and mounting to a target location. Such a display device may be deployed on a vehicle, for instance, as part of a vehicle navigation, communication, and/or entertainment system.
